Title: Protective system for high voltage transformers and the like
IPC: H01F27/40
Filed: 1937-07-26
Abstract: 499,817. Protective cut-out arrangements. BRITISH THOMSON - HOUSTON CO., Ltd., KINMAN, T. H., and HIBBERD, R. G. July 26, 1937, No. 20640. [Class 38 (v)] A protective arrangement for a transformer comprises a pick-up coil or equivalent device made to resonate at one of the high frequency resonant peaks of the transformer and / or circuit associated therewith, and arranged within the transformer tank so as to be capable of receiving energy at the frequency to which it is resonant while being shielded so as to be unresponsive to extraneous energy of that frequency, amplifying means for the energy induced in the coil, and a protective device operated from the output of the amplifying means. The high-frequency resonant peaks are due to inherent inductive reactance and capacity of the transformer windings or winding sections. The pick-up coil may be replaced by a short rod or wire insulated at one end and connected at the other end through a limiting resistance R to the grid of the amplifying valve T, which may be of the type known under the Registered Trade Mark " Thyratron.'' Anode and grid of the valve arc connected to opposite ends of supply transformer M so as to be supplied with potentials of opposing phase, the grid being adjustably biassed by a slider resistance S so that normally no ionization occurs. The pick-up coil is coupled through condenser G<1>, and an inductance L arranged in the grid circuit has the maximum voltagedrop produced across it over a band of high frequencies corresponding to certain resonant peaks, an arrangement which allows for application to transformers of different types. A relay coil or indicator O is provided in the output-circuit. By enclosing the pick-up coil in the tank or in a screening box in the tank, extraneous pick-up is prevented. A tuned radio-frequency circuit may be formed by winding one or more of the leads connecting the H.T. secondary windings with the terminals in the form of a helix, and this may be coupled to a circuit comprising' a single loop of wire connected across condenserterminals which are also connected to a relay and valve preferably arranged in a screened box outside the tank, the valve being a highvacuum one. Brush discharge in either terminal or winding end sets up oscillations in the tuned circuit of a frequency determined by the inductance and capacity. Specification 336,184, [Class 38 (iv)], is referred to.

Title: Improvements in or relating to the manufacture and production of electrical resistors with a low inductance
IPC: H01B1/00
Filed: 1943-12-14
Abstract: 570,026. Resistance coatings and deposits. JOHNSON, MATTHEY, & CO., Ltd., BOX, E. R., and WYETH, E. J. Dec. 14, 1943, No. 20918. [Class 37] A resistor having a low inductance comprises a thin sheet of insulating material, such as mica, having a design in the form of a continuous line applied to one side and a mirror-image of the design applied to the other side in such a position as to be coincident with the first design, both designs comprising a thin conducting layer of a metal or an alloy and contacting at one edge of the sheet. In the example shown in plan in Fig. 1 and in side elevation in Fig. 2 a thin sheet of mica 1 has applied to its upper side a layer of silver in the form of two relatively wide bands 2, 3 joined by a zig-zag line 4. On the underside of the sheet 1 there is applied another layer of silver 2a, 3a, 4a which is a mirror-image of the layer 2, 3, 4, the two layers being coincident. The bands 3, 3a contact over the edge of the sheet 1. Connections are made by a clamp to the bands 2, 2a, the current passing through the zig-zag line 4 at all points in the opposite direction to its passage through the line 4a so that the resistor has an extremely low inductance. Suitable metals and alloys for the layers are gold, silver, platinum, palladium and alloys of these with each other. Small quantities, e.g. up to 10%, of base metals may be added to increase the resistance. The metal or alloy may be applied in the form of a continuous thin strip which is caused to adhere to the mica by means of an adhesive such as a thermosetting plastic. Alternatively the metal or alloy may be applied in the form of a fine powder mixed with a liquid screen printing medium into a paste which is applied to the mica through a stencil attached to a meshed printing screen. Volatile solvents are removed by drying and the coated mica is heated to a temperature at which the organic matter is burned away leaving a continuous thin layer of metal firmly adhering to the mica. The finely divided metal in the paste may be replaced by a metal compound or compounds decomposable by heat to produce a residual non-oxidized metal or alloy film. Examples of such compounds are gold, platinum, palladium and silver oxides, hydroxides, amino compounds and salts of organic or volatile inorganic acids (other than halides). In order to improve the adherence of the film the paste may contain a flux such as lead or bismuth silicate, borate, or borosilicate or mixtures of these. The liquid screen-printing medium may comprise a solution of cellulose nitrate or ethyl cellulose in ethyl, amyl or butyl acetate, lactate, or phthalate with or without a plasticizer such as diethyl or dibutyl phthalate, medicinal paraffin, castor oil or methyl abietate.
